How To Use OTDR?
Aug 14 , 2020
HOW TO USE OTDR? What is the most important thing to our OTDR? It must be looking at the graph and analyzing the curve. Then you can determine the condition of the line according to the curve. The operation mode and key function of each machine are basically different. First of all, we have to understand the basic operation and the key functions. We need to understand the most basic aspects of the...

How To Use The Optical Power Meter?
Aug 20 , 2020
Optical power meter refers to an instrument used to measure absolute optical power or the relative loss of optical power through a section of optical fiber. Simply put, it is to measure the attenuation of the optical signal after fiber transmission. Simple instructions: 1. When measuring the absolute optical power with the optical power meter, just connect the light source and look at the value in...

The Basic Principles of OTDR
Oct 15 , 2020
OTDR is called Optical Time Domain Reflectometer, which injects narrow light pulses into the fiber end face as a detection signal. When the light pulse propagates along the fiber, the backscattered part of Rayleigh scattering everywhere will continue to return to the incident end of the fiber. When the optical signal encounters a crack, Fresnel reflection will occur, and the back reflected light w...

How to Use VFL
Nov 04 , 2020
VFL is very easy to use. The steps to use a VFL are provided as following: Step One: remove the plastic connector covers from both ends of the test fiber cable. Step Two: connect the fiber optic visual fault locator one end of the fiber. Press the tester button and observe that light emanates from the other end of the fiber. This gives a simple indication of the continuity of the fiber link. Step ...

Precautions for using VFL
Feb 03 , 2021
Visual Fault Locator are also called VFL, pen-type red light sources, visible light detector, optical fiber fault detectors, optical fiber fault locators, etc. Most of them are used to detect fiber breakpoints. According to their shortest detection distance, they are divided into: 5Km, 10Km, 15Km, 20Km, 25Km, 30Km, 35Km, 40Km, etc. Driven by a constant current source, a stable red light is emitted...

Why we need OCID?
Apr 23 , 2021
As demand for optical fiber increases day by day,the numbers of fibers in a single optical cable can be as many as 2096 individual fibers.As more fiber cables are buried underground,it becomes extremely dificult for the telecom engineers and technicians to manage the cables because cables may take different pathways, or be labeled incorrectly. As vast large number of optical cable being deployed b...

What is OTDR Blind Area?
Aug 26 , 2021
Why does the blind area come up? The OTDR produces a blind area because the OTDR's detector is temporarily "blinded" by the high intensity Fresnel reflection light (mainly caused by the air gap between the OTDR connections). When the high intensity reflection is produced, the power of the photodiode is more than 4000 times higher than the backscatter power. Thus, the reflected light signal receive...

How to reduce the fusion splicing loss?
Apr 28 , 2022
The size of the loss is a very important technical indicator of the optical fiber fusion splicer. The lower the loss, the higher the precision of the machine, which can support longer distance fusion splicing. The more perfect the fusion point, the longer the service life. 1. The fiber cleaver cutting angle of the fiber is very important. At present, most of the optical fiber fusion splicers are f...

OTDR test with light
May 24 , 2022
What is OTDR test with light? When testing with the wavelengths of 1310nm, 1490nm and 1550nm of common OTDR, it is necessary to require that there is no communication optical signal in the line under test. Forcing the test with light will burn out the internal detector of the OTDR. With light test, the OTDR can still complete the test without interrupting the signal light in the line during the te...

What is the difference between the six motors and four motors of the fusion splicer?
Jun 07 , 2022
Maybe many friends' cognition of splicing machines and motors only exists in the more the better. This is true, but too general. Today we will talk about why six-motor splicing machine have lower losses and better performance. 1. Four motor fusion splicer, with two propulsion motors and two core-adjusting motors. The six-motor splicing machine also has two focus motors. The most intuitive view is ...
